Installation standards for self-generating power systems and determination of holding distance/power output of generators.

Installation standards for self-generating power systems and determination of holding distance/power output of generators.

Introducing with tables and figures! Please use this as a reference for the installation of self-generating systems and generator output.

We will introduce the installation standards for self-generating power systems and the determination of generator output. As installation standards for equipment, there is a "Quick Reference Table for Firefighting Equipment Requiring Self-Generating Power Systems," which categorizes types of fire protection objects and firefighting equipment. Regarding the holding distance, it is stipulated that the installation must have a holding distance based on the "Emergency Power Source (Self-Generating Equipment) Testing Standards," considering operational and inspection aspects. Furthermore, regarding the determination of generator output, please perform capacity calculations according to the Fire Department Notification No. 100 issued on August 1, 1988. We hope this information will be helpful for your installation and generator output considerations. *For more details, please refer to the PDF document or feel free to contact us.
